Neos, I appreciate that you have given consideration to my critique. This is good. Open mindness is extremely important.

I would like you to consider something else: what is the source for these interpretations of etymology? You say here that, perhaps there is one of two direct Greek origins for "alter," for example, or a Latin origin. I insist (as I believe will the majority insist) that the Latin origin is the correct one.

How do I know this?

It is the source of my understanding. I can cite this reference from Webster (and countless others, including Latin dictionaries) that demonstrate the origin of "alter" :

I am sorry but I can't be polite to someone who makes a mockery of linguistics, shames Greeks and tells the world that there were people who had no word for i.e. "milk" until they got it from the Greeks I suppose. Or changed the word they had and adopted a word derived from the Greek.
